Racing-Oriented Cooling for 540 Motors

For racers and tuners chasing consistent motor temperatures, the 3Racing 540 Motor High Finger Heat Sink with Fan delivers targeted cooling. The design pairs extended finger fins with an integrated fan to accelerate heat transfer from the motor can during prolonged high current events.

Technical Highlights

  • Directed Airflow: The fan provides steady directed cooling to minimise temperature rise under sustained load.
  • Maximised Fin Area: High finger fins increase surface area for faster conduction away from the motor core.
  • Precision Build: Manufactured with attention to fit and durability for repeated race use.
  • Straightforward Installation: Compatible with common 540 motor mounting patterns to reduce setup time at the bench.

What cooling gains can I expect in race conditions?

Gains vary by motor and load, but the high finger profile plus forced airflow typically reduces steady state temperatures versus stock cans, aiding consistency between runs.

Is the fan suitable for direct ESC fan headers used in racing setups?

Yes, the fan is designed to work with standard ESC fan headers or a receiver channel, but confirm voltage compatibility and connector type with your electronics before fitting.

Any recommended checks for race prep?

Verify secure mounting, clean fin surfaces, and confirm the fan spins freely; small checks like these preserve cooling performance and prevent issues during practice or heats.
